Contents of a Residential EPC

Energy Performance Certificate commonly referred to as EPC gives you all the information that you need about a particular property’s energy use and typical energy costs. It also provides you recommendations about how to reduce energy use and save money. An EPC gives a property an energy efficiency rating from A (most efficient) to G (least efficient) and it is valid for 10 years. It is a legal requirement to have an EPC for potential buyers and tenants before you market your property for selling or renting.

Estimated Energy Costs

These are current costs in £ which explains how much you are currently spending for heating, hot water, and lighting. It also explains how much your estimated cost will be for the next 3 years. This does not include the portable equipment that you plug tot the power sources such as TV, computers, microwave oven, etc. It also shows an average figure of how much you could save in a span of three years time by adapting to the energy-saving measures shown in this document. We calculate the energy consumption of your property based on a standard occupancy not on actual occupancy. This is independent of the number of people living in your household, how many domestic appliances you own (such as washing machines and refrigerators) and how efficient they are and how you choose to heat your home (i.e. individual temperature settings and how long it is heated during the day or night). This allows prospective buyers or tenants to compare the energy rating of buildings on a like for like basis.

Rating Chart

This is the chart that most people will be used to seeing and which is often, mistakenly, referred to as “The EPC”. Whilst very important, they only constitute a small part of the whole document. They provide a simple snapshot of how well the property does in terms of its energy efficiency.

The calculation of the energy ratings on the Energy Performance Certificate (EPC) are based on the RdSAP procedure which is derived from the UK Building Research Establishment’s Domestic Energy Model (BREDEM), which was originally developed in the 1980s and also underlies the NHER Rating. EPC is only to be produced by Domestic Energy Assessors who are registered under an approved certification scheme. This chart presents the energy efficiency of your house on a scale of A to G. The most efficient homes – which should have the lowest fuel bills – are in band A. The certificate uses the same scale to define the impact a home has on the environment. Better-rated homes should have less impact through carbon dioxide (CO2) emissions. The average property in the UK is in band D or E for both ratings.

Top Actions to Save Money

These could be considered as the immediate recommendations from the software that could be achieved easily to reduce the carbon emission and to improve the energy efficiency of the property. However, a complete list of recommendations can be found on the following page number 3. This also explains the cost for the improvement measure and also explains whether it is available with the Green deal or not (How to obtain Green deal funding and the color-coding of the availability is explained later in this document). It also gives you a better idea of how much you will be saving in the coming 3 years if you implement the measure. This chart should be compared in accordance with the carbon emission into the atmosphere to understand the responsibility that we all have to save the planet.

Summary of your homes Energy Performance-related features

Each fixed factor that has a direct impact on the energy performance of the building is compared in this section and it is displayed with stars on the right column to represent how efficient they are. Five stars mean it is very efficient and needs no more improvement.


This section shows what the recommended measures that can be taken to improve the property’s energy efficiency. We do not recommend that you carry out any of these recommendations yourself. We would strongly advise you to seek a professional within the area of expertise required to discuss how the improvements could be made. Please make use of the information in the green deal explained section to get expert help in installing measures. Green deal finance is available for the measures shown in the right column and can be discussed with a green deal provider..

You can make energy-saving improvements to your home or business without having to pay all the costs up front through the Green Deal.

insulation – eg loft or cavity wall insulation
double glazing
renewable energy technologies – eg solar panels or wind turbines

Depending upon the recommendations on the EPC certificate you could get one of the green approved installers to get the work done for you. He will be able to suggest the mode of payments on how to distribute the payments over time and also to avoid the upfront cost for you. All Green Deal organizations must be approved.

The golden rule of the green deal always gives you the protection of no payments more than the current spend on the fuel bills. The Golden Rule is the Government’s definition for the maximum amount of loan which can be applied to a home through Green Deal. Put simply, the amount you save on your energy bills every year should be more than the cost of the Green Deal repayments made through your electricity bill. EPCs give information on how to make your home more energy-efficient and reduce your energy costs. All homes bought, sold or rented require an EPC and they will contain key financial information about the Green Deal.

About the Document

This section explains where the data will be lodged how to download the certificate and how the collected data would be used.

This also gives you the details about the assessor and his contact details.

Impact of the building on the Environment

This tells you your current and potential energy use and carbon dioxide emissions per year. Higher the rating lesser is the impact on the environment. This means that you are playing your part in saving our planet. Please consider installing other recommendations to further reduce the carbon emission to the atmosphere.
